Abstract
The utility model discloses a dry non-crystal alloy power distribution transformer which is composed of an outer shell, an iron core and a coil, wherein the iron core is group sheets composed of non-crystal alloy sheets, the group sheets are bent into a square shape and the joints of the group sheets are in an overlapping mode between the sheets. An insulating plate is arranged between a year coil of the iron core and the coil, which makes the no load loss of the transformer less. The iron core and the coil are replaced conveniently, and the volume of the transformer is shrunk.
Description
The utility model relates to a kind of dry type amorphous alloy distribution transformer.
At present, domestic-developed and the oil immersed type three-phase amorphous alloy distribution transformer of having developed 30-500KVA, though technical indicator is relatively good, economic index is not as people's will, the market receiving ability is limited, simultaneously, in urban distribution network, oil immersed type three-phase distribution transformer is if leakage of oil, can bring contaminated environment, and being difficult for fire-proof and explosion-proofly, so national regulation, oil immersed type three-phase distribution transformer do not allow to enter skyscraper.The dry type three-phase silicon steel distribution transformer of domestic production now is many with the iron amount, volume big, no-load loss is big, cost is big, when coil breaks down with defective, can not keep in repair and can only integral body scrap.
The purpose of this utility model is to provide that a kind of no-load loss is little, coil easy accessibility, dry type amorphous alloy distribution transformer that volume is little.
For achieving the above object, dry type amorphous alloy distribution transformer of the present utility model is made up of shell, iron core, coil, and iron core is square for the group sheet of being made up of amorphous alloy film curves, and its interface is the overlapping mode of sheet and sheet; Be contained between coil on the iron core and the coil and be provided with insulation board.
After adopting such structure,, make the magnetic flux density increase because that iron core adopts the group sheet of being made up of amorphous alloy film to curve is square, its interface is the overlapping mode of sheet and sheet, just can realize the easy disassembly coil, between coil and coil, be provided with insulation board, can dwindle the volume of transformer.
Fig. 1 is the schematic diagram of a kind of embodiment specifically of the present utility model, the i.e. single-phase amorphous alloy distribution transformer structural representation of dry type;
Fig. 2 is the schematic diagram of concrete another embodiment of the present utility model, is dry type three-phase amorphous alloy distribution transformer structural representation.
Fig. 3 is the structural representation of iron core of the present utility model.
Be made up of shell 1, iron core 2, coil 3 as Fig. 1, Fig. 2, dry type amorphous alloy distribution transformer of the present utility model shown in Figure 3, iron core 2 is square for the group sheet of being made up of amorphous alloy film curves, and its interface is the overlapping mode of sheet and sheet; Be contained between coil on the iron core and the coil and be provided with insulation board 4.Need take out stitches and enclose 3 o'clock, take out iron-core workpiece from shell 1, open the interface of iron core 1, take out coil 3, this just can reach the effect of changing iron core 2, coil 3 easily.
